I want to test whether an individual's grouping (categorical of which there are 4 separate groups) together with their response to another question (likert type, so assumed ordinal) affects their preference for a range of strategies (which they individually ranked from 1-6)

Would either ordinal regression or multivariate analysis be suitable to test this? My data is not normally distributed, so would need to use non-parametric tests.

  • $\begingroup$ Sounds like two have two categorical variables, and you want to test association. Anything wrong with chi-square test? $\endgroup$

  • $\begingroup$ In your question, you don't have enough variables for multivariate analysis. But you can just use the ordinal as response for a ordinal regression model. $\endgroup$

  • $\begingroup$ Thank you - yes I realised after I posted that for a multivariate analysis I would need two DVs, and I only have one, so you would say ordinal regression is best to use for influence of two IVs (together) on one DV? $\endgroup$

  • $\begingroup$ From the OP I understand there to be 6 dependent variables: each strategy that receives a rank. $\endgroup$

  • $\begingroup$ @rolando2 Maybe. That could also be a single ordinal variable, with values from 1-6. $\endgroup$

As noted in the comments, multivariate analysis isn't possible here.

When the dependent variable is ordinal (as yours is) then ordinal logistic regression is a good starting point, at least, but it makes an assumption of proportional odds. If that assumption is violated, then the most common choice is multinomial logistic regression, but there are some other choices too, such as the partial proportional odds model.

You might also try a tree, or one of the methods based on trees.
